⚙️ Heli-cact-er ⚙️

This STEM activity kit is perfect for kids that love STEM and crafts. Kids can build driven kinetic “bots” using LEGO bricks and paper crafts. These STEM projects make learning about kinetic elements and mechanical engineering very fun! 😎

What is LEGO Gear Bots?

Build S.T.E.M.-driven models, such as DJ Bubbles (an octopus spinning records), a pterodactyl, a yeti, and much more! Kinetic sculptures, or automata, are mechanically engineering toys that move when you crank the handle on the side. They move through a series of axles, cams, and cranks that work like the pistons in an engine. Each model includes a papercraft character that you fold and link with LEGO elements.

  • Build 8 physics-driven kinetic creatures using LEGO Technic bricks and papercraft.

  • Includes every LEGO element you need!

  • S.T.E.M. content about axles, cams, cranks, engineering in everyday machines is included.



  • Comes with a book which includes step-by-step instructions.

  • So many STEM topics to learn/discuss.

  • Easy instructions.

  • Fun for the kids all ages!


  • Some of the paper crafts are very fragile.

  • Needs storage. It comes in a small size box.



  • Adult supervision required for any of these activities. Please supervise and make sure children participating are safe. Read instructions and the safety labels from each used materials.
